METHOD OF rnonvomo WIRE-GLASS AR'r'ro'Lns.

To all when: it may concernp;

Be it known that I, Jomr I. ARBQGAST, a citizen of the United Statesfof America, re-

siding at Pittsburg, in the county'of Alle-' gheny and State of Pennsylvania, have invented certain new and useful Improvements in Methods oiProducing ire-Glass Articles, of which the following is a specification, reference being had therein, to the. accompanying drawing.

This invention rel tes to a niethod of produeing'wireglass articles, and. its primary object is to provides-novel method whereby a great variety of-articles'may be-inexpen- I signed for the production of siyely formed fronrwire glass;

-The improved method is especially:.-de-'= wire {glass shades -forelect1ic and other lights, such as arc-shades, cone-shades andfadon e-shadesr and" alsoior producing various fadon estic utilities, its-sanitary basins, bowls and the enerallyjstated, I

consists in assembling Qiysp acing, 1 ogether to glass of suitabl is crime-13;

suitable furnace to" cause the glass to colla so and conform tothefshape, or contour o the pattern or former. After. thearticle .thus formed has cooled, th'epattcm or former is removed, leaving a complete article of glass with-wire.ineshembedded therein.

The invention will bejully described hereinafter in comiection 'with theaccompanying drawing which forms a part of this specification, and its novel features set forth in the ap ended claims. M

Having fully described my invention what I claim and desire to secure by Letters Pat-9 entis,'.-"

1 The herein-described method of1 producing wire glass articles,-'consisting of assembhng two layers of glass of the required size and shapeto form the article to be produced, with an interposed layer of wire mesh; placing said layers of lass and wire mesh upon a former; and t en subjecting said layers to heat within a furnace to cause them to anialgamate, and during amalgamation to assume the shape of the former,

2. The hereindescribed method of producing wire glass articles, consisting of assembling two independent layers of glass of predetermined size and shape, with an interposed la er of wire mesh of similar size and shape, p acing said layers of'glass and wire mesh upon a pattern or former; then-subjecting them to heat to cause thelayers'to col-a layer of wire mesh;

pattern or former, t en su jecting said layers lapse-and amalgamate upon the pattern or former and conform to the shape-thereof; and finally removing the former after the glass has cooled 3. The herein-described 'method of;.producing wire glass articles consisting of as-' sembling two layers of glass of pre-deter-- mined size and sha e, with an interposed aein said layers upona rst to a gradually increasing heat, then to an annealing'heat, and finally to a gradually decreasing heat whereby the assembled layers of glass and wire mesh are caused to conform to the shape of the pattern or former and amalgamate during such shaping.-

4. The erein described method of producing wir glass articles, consisting of assemblmg two circular plates or layers each formed with a central opening, with an interposed circular layer of wire mesh also formed with a central opening registering with the openings in the glasslayers; placing said assembled layers of glass and wire mesh upon a pattern or former, and then subjecting them to heat to cause the glass to collapse upon the pattern or former and assume the shape thereof. e

5. .The herein-described method of. producing wire glass articles, consisting of assembhng two circular glass plates or layers each formed with a central'circular opening,

with an interposed layer of wire mesh also formed with a circular central opening registeringwlth the openings in the glass layers,

placing said assembled layers of glass and wire mesh upon a attern or former, and then sub ecting them 11st to a gradually increasing heat, then to an annealing heat to cause.

the glass to collapse and conform to the shape of the pattern or former and finally to a gradually decreasing heat.

,6. The herein described method of produci'11g wire'glass articles consisting of assembling two separate plates or 'layersof glass of the required size and shape to produce the desired article with an interposed layer of .wire mesh, arranging said asesmbled layers I upon a'pattern or former andthen SlObJeOtlIlg them to heat to'c'ause the glass and wire mesh to collapse and amalgamate and during tour of the pattern "or-former; Y
